Three sacraments are necessary for salvation. Two of them are necessary to the individual; Baptism, simply and absolutely; Penance, in the case of mortal sin committed after Baptism; while the sacrament of orders is necessary to the Church.
This post highlights the group of three Sacraments (Baptism, Penance and Holy Communion).
All can be received in desire
(Highlighted in red). None is singled out to be different. This is why the canon refers to them
as a group.
If any one saith, that the sacraments of the New Law are not necessary unto salvation, but superfluous; and that, without them, or without the desire thereof, men obtain of God, through faith alone, the grace of justification;-though all (the sacraments) are not indeed necessary for every individual; let him be anathema.The Council of Trent-The Seventh Session-Canon IVBAPTISM: By which words, a description of the Justification of the impious is indicated,-as being a translation, from that state wherein man is born a child of the first Adam, to the state of grace, and of the adoption of the sons of God, through the second Adam, Jesus Christ, our Saviour. And this translation, since the promulgation of the Gospel, cannot be effected, without the laver of regeneration, or the desire thereof, as it is written; unless a man be born again of water and the Holy Ghost, he cannot enter into the Kingdom of God.The Council of Trent-The Sixth Session-Chapter IVPENANCE:As regards those who, by sin, have fallen from the received grace of Justification, they may be again justified, when, God exciting them, through the sacrament of Penance they shall have attained to the recovery, by the merit of Christ, of the grace lost: for this manner of Justification is of the fallen the reparation: which the holy Fathers have aptly called a second plank after the shipwreck of grace lost. For, on behalf of those who fall into sins after baptism, Christ Jesus instituted the sacrament of Penance, when He said, Receive ye the Holy Ghost, whose sins you shall forgive, they are forgiven them, and whose sins you shall retain, they are retained. Whence it is to be taught, that the penitence of a Christian, after his fall, is very different from that at (his) baptism; and that therein are included not only a cessation from sins, and a detestation thereof, or, a contrite and humble heart, but also the sacramental confession of the said sins,-at least in desire, and to be made in its season,-and sacerdotal absolution; and likewise satisfaction by fasts, alms, prayers, and the other pious exercises of a spiritual life; not indeed for the eternal punishment,-which is, together with the guilt, remitted, either by the sacrament, or by the desire of the sacrament,-but for the temporal punishment, which, as the sacred writings teach, is not always wholly remitted, as is done in baptism, to those who, ungrateful to the grace of God which they have received, have grieved the Holy Spirit, and have not feared to violate the temple of God. Concerning which penitence it is written; Be mindful whence thou art fallen; do penance, and do the first works. And again; The sorrow that is according to [Page 42] God worketh penance steadfast unto salvation. And again; Do penance, and bring forth fruits worthy of penance. The Council of Trent-The Sixth Session-CHAPTER XIV.HOLY COMMUNION:Now as to the use of this holy sacrament, our Fathers have rightly and wisely distinguished three ways of receiving it. For they have taught that some receive it sacramentally only, to wit sinners: others spiritually only, those to wit who
eating in desire that heavenly bread which is set before them, are, by a lively faith which worketh by charity, made sensible of the fruit and usefulness thereof: whereas the third (class) receive it both sacramentally and spiritually, and these are they who so prove and prepare themselves beforehand, as to approach to this divine table clothed with the wedding garment.
